Warner expected to miss 1-2 weeks

ESPN reports that the 49ers expect LB Fred Warner to miss 1-2 weeks with the hamstring strain he suffered in Sunday's win over the Vikings. Fellow LB Dre Greenlaw is day-to-day, Cam Inman of the San Jose Mercury News reports. That leaves Azeez Al-Shaair as the best bet to lead San Francisco LBs in playing time for the Week 13 clash with Seattle.
